I recently successfully replaced the digitizer on my iPad 6th Gen (WiFi) after using for about 2 days, the iPad rebooted itself, and now WiFi switch is turned off and greyed out, and Bluetooth just keeps searching for devices and can’t find anything. I tried resetting network settings, rebooting my gateway modem, and restoring to factory settings. Nothing worked. What I am wondering is would a bad antenna cause these issues, or if the antenna is bad would I just have crappy reception?
It’s possible that you may have successfully repaired the screen but damaged the connection on the iPad itself. If it’s greyed out from my experience that generally means that someone inside the iPad is damaged. Only way to fix it is to open it up again and check
